ActionScript 2.0 :: How To Get Cursor To Disappear When Rollover Object

I want the cursor to disappear when it rolls over an object, then reappear when it rolls off. It works when I run it in Flash, it works when I view the html in Internet Explorer, it DOESN'T work in Netscape. The cursor disappears and doesn't come back till you move it out of the navigator window. Here's the code:

on (rollOver) {
loadMovie("movie.swf", place);
mouse.hide();
} on (rollOut) {
loadMovie("blank_movie.swf", place);
mouse.show();
}
